|discussion=<p>Subspecies beringensis was formerly considered to be part of Dryas octopetala var. octopetala (R. Elven et al., http://nhm2.uio.no/paf/). This subspecies forms hybrid swarms with D. alaskensis and D. integrifolia in Alaska and eastern Siberia (Elven et al.). Dryas incanescens Juzepczuk and D. ajanensis Juzepczuk var. incanescens (Juzepczuk) Kozhevnikov have been misapplied to subsp. beringensis.</p>
